To aZZVwhoi/n, it may concern:

Be it known that we, WILLIAM JAMES LANE and GEORGE LANE, citizens of the United States, residing at Poughkeepsie, county of Dutchess, State of New York, have invented certain new and useful Improvements in Hydrocarbon-Burners, of which the following is a specification.

' Our invention relates to hydrocarbon-burners of the type adapted to be fed with a mixture of ahydrocarbon fuel and air under pres-- 'regards the burner and casing that the gas and air passing through it on the way to the burner will be but slightly heated.

The object of our invention is through the instrumentality of the supply-tube to moderately heat the gas and air delivered into it, thereby expanding said bodies and edecting their thorough admixture before delivering said combined bodies into the burner.

The object of our invention so far as relates to the construction of the burner is by reason of the spaced burner-tubes to limit the bodies of air delivered on each side of the burner-tubes to such lthin bodies as are necessary to support the combustion of the hydrocarbon fuel emitted from the burneropenings of the lateral tubes.

The accompanying drawings will serve to illustrate our invention, in which- Figure 1 is a bottom View. Fig. 2 is a ver- Fig.

tical section on the line X -X of Fig. l. 3 is a bottom view showing a moditication.

In the drawings, 10 represents a centrallydisposed tube which we term the heating-v chamber. Disposed laterally as regards this tube are smaller tubes 1l, whose interiors form a part of the heating-chamber.v These tubes are spaced as regards each other, being separated at a slight and limited distance from each other through the air-spaces 12. The upper surfaces of the tubes 10 and 11 are perforated with ne burner openings 13.

burner-injector 15.

The combined area of these openings we prefer to be such that the mingled gas and air fed into the heating-chamber will be slightly retarded in its passage through the burneropenings. The distance between successive tubes 11 We prefer to be suchthat but a thin column of air can pass upward when heated on each side of a tube 11. It is important that the spaces between the tubes 11 shall be proportioned to the 'burner-openings 13, as otherwise too much or too little air will be fed to the iiames from the ignited gas passing from the burner-openings. The size of the burner-openings 13 and the width of the.

spaces 12 can be readily determined by experiment. We would also add that the specic gravity of the hydrocarbon Huid employed, pressure under which the fluid is fed to the burner, dto., will in some sense modify the relative sizes ot' the burner-openings 13 and spaces 12.

Situated under the tube, 10, Fig. 2, or at the side of the burner, Fig. 3, or having other relation relative to the burner where it will not be heated to any appreciable extent by heat conduction or radiation from the burner, is a tube 14, which we term the mixingtube. Located in front of this tube is the In Fig. 2 the mixingtube la is connected to the tube 10 through the coupling 16. In practice we prefer to form tube 10 and coupling 16 as one piece Gas and air are projected into the mixingtube 14:. As this tube is slightly heated, these bodies will be mixed and expanded and reach the heating-chamber 10 in this condition and under a slight pressure. When the bodies flow into the heating-chamber, which, as before stated, is composed of the cavities of the tubes 10 and 11, the gas is expanded and heatedand ows upward and out of the burner-openings 13 and when ignited has oxygen fed to it by the lateral air-currents passing up through the spaces at the sides of the tubes 11.

We have found it convenient in the practi- IOO cal construction of our invention to make the mixing-tube of approximately the same size as the heating tube, although it may be smaller. We have also found that the heating-tube may be either perforated or non-perforated along its upper surface.

The practical and essential feature of our invention may be said to consist in a construction in which the hydrocarbon gases are heated to the required extent, but not to a greater amount, and when fed through the burner-openings and ignited fed with oxygen from thin streams of heated air passing upward between the lateral tubes of the burner.

We consider any construction which would embody the above features of invention as within the intent of our invention and an equivalent for the construction described.

Having thus described our invention, we claim- 1. A hydrocarbon-burner comprisinga centrally-disposed tube, having one portion of its length located outside of the combustionchamber in which the burner is situated, a series of spaced lateral tubes so arranged as regards each other as to permit but thin currents of heated air to pass upward on each side of said tubes, and a tube located ont of the combustion-chamber within which the burner is situated but in such position as regards said burner as to be heated thereby, said tube open at one end to the atmosphere and communicating at its opposite end with the portion of the centrally-disposed tube which is exterior to the combustion-chamber.

2. A hydrocarbon-burner comprising a casing, a tube arranged centrally and transversely of said casing, and having a portion of its length extending beyond the casing, a series of spaced lateral tubes projecting from said central tube, and so arranged as regards each other as to permit but thin currents of heated air to pass upward on each side of the burner-tubes, and a tube located outside of the casing but in such relation to the burnertubes as to be heated thereby, and communicating at one end with the atmosphere and at the other end with the portion of the centrally-disposed tube exterior to the casing.

3. A hydrocarbon-burner comprising a casing, a tube arranged centrally and transversely of the interior of the casing, and having a portion of its length extending beyond the casing, a series of lateral tubes projecting from the central tube and so shaped as to conform to the contour of the inclosing casing and arranged in such manner as to have air-spaces between them relatively narrow as regards the diameter of said tubes, and

a tube located exterior to the burner and casing, communicating with the atmosphere at one end and with the portion of the centrallydisposed tube exterior to the casing at the other end.

In testimony whereof We affix our signatures in the presence of two witnesses.
